UniswapV2TWAPOracle Contract

The UniswapV2TWAPOracle is a Solidity smart contract that calculates the Time-Weighted Average Price (TWAP) for a Uniswap V2 pair. The contract utilizes both current and past cumulative prices to generate an average price that is resistant to manipulation.

Methods

1. consult(address token, uint amountIn, uint256 pastBlockNumber)

• Calculates the Time-Weighted Average Price (TWAP) for a given token in a Uniswap V2 pair.

Prerequisites

• Node.js v12+ LTS and npm (comes with Node)
• Hardhat
